This commit switches off forced correct nesting of tags and only keeps
it for font tags. See long explanations in the code for the rationale.

This results in various FATE changes which I'll explain here:

- various swapping in font attributes, this is mostly noise due to the
  old reverse stack way of printing them. The new one is more correct as
  the last attribute takes over the previous ones.

- unrecognized tags disappears

- invalid tags that were previously displayed aren't anymore (instead,
  we have a warning). This is better for the end user

The main benefit of this commit is to be more tolerant to error, leading
to a better handling of badly nested tags or random wrong formatting for
the end user.

Also fix missing dependency.

With this helper API, filters that used the first framesync
helper API can easily be changed to use the new and more
extensible design for filters with a single activate() callback.

These wrappers cost nothing, they make the namespace more
consistent and they will be useful if/when locking becomes
necessary.

I am not entirely sure that this return code is useful,
but having and using it makes no harm.

framesync2 will be the base for the version using activate.
Most of the logic will be the same, but the code cannot be shared.
Copying the file initially without change will make the diff
easier to read.

This reverts commit 04aa09c4
and reintroduces 0ff5567a that
was temporarily reverted due to minor regressions.

It also reverts e5bce8b4 that fixed FATE refs.
The fate-ffm change is caused by field_order now being set
on the output format because the first frame arrives earlier.
The fate-mxf change is assumed to be the same.
